Endovascular Coiling for a Ruptured Proximal Lenticulostriate Artery Aneurysm

Aneurysms of the lenticulostriate artery (LSA) are rare lesions that are categorized into either proximal (at the junction of the middle cerebral artery trunk) or distal (within the basal ganglia).[1] These lesions have been reported against the background of a diverse array of pathologies including hypertension,[2] vascular malformations,[3] moyamoya disease, substance abuse, systemic lupus erythematosus, ventricular neurocytoma, and Sneddon’s syndrome;[4] however, most cases are idiopathic.[1]
